प्रश्न
A strong sound signal is sent from a ship towards the bottom of the sea. It is received back after 1s. What is the depth of sea given that the speed of sound in water 1450 ms–1?
उत्तर
Velocity of sound in water = `"Distance travelled by sound"/"Time taken"`
Depth of the sea, d = velocity × time
d = `"vt"/2` = `(1450xx1)/2` = 725 m.

The Velocity of sound is high in gases than liquids.
Assertion: The speed of sound in air is less than the speed of sound in solid.
Reason: If we increase the temperature of medium, the speed of sound increases in any medium.
The speed of sound in a gaseous medium depends on the nature of the gas.
